The appropriate design of feeders in a rigging system is critical for ensuring efficient compensation for solidification shrinkage. thus eliminating (shrinkage-related) porosity and contributing to the production of superior quality castings. In this study. a multi-objective optimisation framework combined with Computational Fluid Dynamics (CFD) simulations has been introduced to inve... https://balboasurfandsstylers.shop/product-category/kids-hat/
